Description of problem:
I just upgraded to kernel-2.6.15-1.1830_FC4 from 2.6.14-1.1656_FC4
When starting the new kernel I get a lot of messages before the "Welcome to Fedora" message. It was to quick for me to read them, but I got the impression that it was performing some hardware checks.
Then it continued, but just before the Rh-graphical boot should start I get a dump and a counter that the machine will continue in xxx seconds. when the counter reaches zero, a segentation fault is encountered.
rebooting into 2.6.14-1.1656_FC4 is still possible.

Version-Release number of selected component (if applicable):
kernel-2.6.15-1.1830_FC4
How reproducible:
Always
Steps to Reproduce:
1.upgrade to kernel2.6.15-1.1830_FC4
2.reboot
3.
Actual Results: see description : failure to boot
Expected Results: nice smooth boot into the new kernel
Additional info:

can you capture that dump somehow ? Even a digital camera picture would be great.
(If you can, add 'vga=791' to your boot command line, and you'll also get a
smaller font, so I'll be able to read more of the backtrace).
Thanks.

The problem becomes rather weird:
I can boot now, but it crashes in the same (or simmilar?) way when shutting
down/rebooting (I attached an image of the screen when it hangs)
What changed bewteen friday and now:
-I performed a selinux relabeling
-I installed newly released updates

I installed 2.6.15-1.1833_FC4 today. The first time boot it hanged just before
starting X11. Only after rebooting in an older kernel I could boot into the 1833
kernel, but when shutting down it hangs just when performing the "halt system".
Now I Half solve the problem when booting into another kernel, but what will
happen when I upgrade in the next weeks to FC5? Do I run into the same problems
without the possibility to boot into another kernel?

[This comment added as part of a mass-update to all open FC4 kernel bugs]
FC4 has now transitioned to the Fedora legacy project, which will continue to
release security related updates for the kernel. As this bug is not security
related, it is unlikely to be fixed in an update for FC4, and has been migrated
to FC5.
Please retest with Fedora Core 5.
Thank you.

A new kernel update has been released (Version: 2.6.18-1.2200.fc5)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.
This bug has been placed in NEEDINFO state.
Due to the large volume of inactive bugs in bugzilla, if this bug is

In the last few updates, some users upgrading from FC4->FC5
have reported that installing a kernel update has left their
systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed. See bug 207474 for further details.
If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.
If this bug has been fixed, but you are now experiencing a different
problem, please file a separate bug for the new problem.
Thank you.
